A certain amount of chlorine gas was placed inside a cylinder with a movable piston at one end. The initial volume was 3.00 L and the initial pressure of chlorine was 1.30atm . The piston was pushed down to change the volume to 1.00 L. Calculate the final pressure of the gas if the temperature and number of moles of chlorine remain constant

1 answer

Use P1V1=P2V2

Since you don't know the P2 just plug in all of the known factors:

(3.00L)(1.30atm)= (1.00L)P2

Solve for P2

3.90=1

P2=3.90atm
